Very frustrating Microstation can be...
Only today > I have had all my editing tool pop up windows appear half off the desktop screen, and they do not wish to move into view when I try to pull them down..
Furthermore My (pdf) Print Box does not wish to appear at all.... Yesterday all was working fine.
Following Wiki's may be of help, please also provide the version number being used if further assistance is required.
The Print Dialog will not display
Dialog box cannot be moved or located
Dialog/Toolbox does not open or is missing
If the above do not help, then you could try restoring MicroStation to Factory Settings
